Sigh...and, as far as I know, nobody took the bait and made an 
implementation- dependent pragma to do Fortran-friendly arrays.

I'm still rockin' on my hobbyhorse, waiting for some Ada company
to say "Mike, we really talked to a good sample of all those 
engineers out there beyond DoD, and concluded that this feature
was not worth the investment."

Did anybody do it? There are a _lot_ of Fotranners out there, in
organizations with lots of money (the DoE labs, for example). Might 
have been a lucrative market. Did _anyone_ try to tap it?
